Excel Calculations in Your Zaps
Zapier moves your data between apps. SpreadAPI does the math. Add real Excel calculations to any Zap — your formulas, your business logic, exact results. No code step, no reimplementation.
Zapier Moves Data — But Who Does the Math?
Zapier connects thousands of apps, but when a workflow needs to calculate a price, a commission, or a quote, you're stuck. The Code step means rewriting your Excel model in JavaScript. Your spreadsheet already does this.
The Code Step Trap
Rebuilding a pricing model in a Code by Zapier step means rewriting Excel formulas by hand — and maintaining them in two places forever. They drift apart.
The Copy-Paste Detour
Exporting numbers to a spreadsheet, waiting for a recalculation, reading them back: slow, brittle, and impossible to trust at scale.
The SpreadAPI Way
Your Excel file becomes a calculation step. The SpreadAPI action sends inputs, your actual formulas compute, results come back as named fields — instantly.
From Spreadsheet to Zap
Publish your Excel model
Upload your spreadsheet to SpreadAPI, mark inputs and outputs, publish. Your formulas stay private — only the parameters are exposed.
Add the SpreadAPI action
In the Zap editor, add an action step, search for SpreadAPI, and choose the Calculate event.
Paste one URL
Connect a new account and paste the service URL from SpreadAPI's Integration panel. Zapier tests it and shows your service name.
Fill fields and run
Your service's parameters appear as fields — dropdowns, numbers, true/false. Enter or map values, test, and the outputs come back as named fields for the next step.
What the SpreadAPI Action Gives You
Self-building fields
The action reads your service definition and renders the right field for each parameter: dropdowns for allowed values, number and true/false fields, percentage hints. No guessing.
Named, typed outputs
Results come back as labeled fields — "Total (incl. VAT)", not a raw blob — ready to map into any following Zap step.
Works in any Zap
Put a calculation between any trigger and any of Zapier's 8,000+ apps: forms, CRMs, sheets, email, Slack.
Formulas stay private
Zapier only ever sees inputs and outputs. Your spreadsheet — the formulas, the margins, the logic — never leaves SpreadAPI.

Frequently Asked Questions
What does the SpreadAPI Zapier integration do?
It adds a "Calculate" action to Zapier that runs a calculation in your published Excel model via SpreadAPI. Input fields are generated from your spreadsheet, and outputs come back as named fields for the rest of your Zap.
Do I need a paid Zapier plan?
The SpreadAPI action is a standard Zapier app — you add it to a Zap like any other. Your Zapier plan governs usage as usual; SpreadAPI adds no extra cost of its own.
Are my Excel formulas exposed to Zapier?
No. Zapier only exchanges input values and calculated results with SpreadAPI. The workbook itself — formulas, hidden sheets, business logic — stays on SpreadAPI and is never transferred.
How do I connect a service?
Copy the service URL from your service's Integration panel in SpreadAPI and paste it into the Zapier connection. One connection points at one published service.
How do percentage inputs work?
Like in Excel: as decimals. 5% is 0.05. Percentage fields are marked with a hint, and the server converts obvious whole-number mistakes automatically on explicitly marked percentage fields.
What does it cost?
SpreadAPI has a free tier to build and test. The Zapier integration itself adds no cost beyond your existing Zapier plan.
Your Excel already knows the answer. Let Zapier ask it.
